Should I switch Birth Control?To Yasmin?

I've been on loestrin fe for... about 6 months or maybe a few more. I'm always tired and I have really bad headaches. Before I was on Yaz, but couldn't afford it. I had no negative side effects from 4 months on yaz. There's a generic yasmin now (a little more estrogen) should I switch? If I was ok with Yaz would Yazmin be ok? Any comments, side effects etc. Thanks!
